Neil Patrick Harris spills on Whoopi Goldberg's sex offer

Neil Patrick Harris and Whoopi Goldberg had the most awkward conversation on air - involving a sex deal.

On The View, the actor recalled working with Goldberg on Clara's Heart in 1988 and how she offered him a strange favour that caught him off-guard.

"You know, I did my first movie ever with Whoopi Goldberg. A movie called Clara's Heart,'" Harris said.

"She told me, I was 15, 16 years old, she told me on my last day of shooting that in 10 years' time she was going to have sex with me," he said.

The audience then cheered and laugh while Goldberg looked back at him with an awkward stare.

"I might've!," she eventually said with a smirk.

Harris asked if she was going to follow-up on her sexual promise.

"He had many questions as a kid, so I said, 'Listen, wait 10 years, and I'll take you through it.' In those days, you could actually have some fun like that. You can't do that now. People get very upset now," Goldberg explained her way out of it.

To dispel rumours, Harris said he wasn't offended by Goldberg's commentary and that he's looking forward to it.
